Project Overview

The Napkings will design an automatic silverware roller that will wrap different utensils together. In the majority of restaurants, it is the server’s responsibility to prepare the silverware sets usually by hand rolling them. As a result, the task becomes extremely tedious and takes precious time away the server has with the customers. The purpose of the automatic silverware roller is to make the job of restaurant servers easier and more efficient. In order to fulfill this purpose, the roller will produce silverware sets at a consistent pace, while maintaining efficiency. The objective is for the server to only have to load the machine once with the appropriate amount of forks, knives, spoons, and cloth napkins needed for one table. From there, the machine will then be able to take one of each utensil and roll them up in a presentable manner. The process will be repeated until all of the needed silverware sets are provided. The intention is to make the machine automatic, yet also simple with little user interaction and low maintence being high design priorities. The less interaction the server has to put into the process, the more time the server can spend doing more important tasks that will improve services.


Proof of Concept

The Napkings’ automatic silverware roller targets the restaurant industry where silverware is usually rolled by waiters. With a few competitors out in the market designing similar machines, the Napkings hopes to create a quick and efficient automatic silverware roller that would save restaurants time and money. Ryan Michaelis was a server himself who understands the tedious task of rolling silverware. The experience of going through such a task allows the team to create a system that is simple and efficient for all users. Additionally, the team has analyzed different solutions from other competitors to be ready for entering the industry. Most solutions developed from other competitors are complex. Main competitors include QuiQsilver and Robowrap. The solutions develop are efficient; however, huge in size. The automatic silverware roller developed by QuiQsilver stands 5.5 feet tall and covers 36 inch by 36 inch ground area. Napkings hopes to develop a product that is smaller in size to allow easier installation for restaurants. Automatic silverware rollers are still a fairly new machine and so has not been fully incorporated into the restaurant industry. The roller developed by Napkings will hopefully be the beginning of automatic silverware rollers within the market.

The main concepts that the Napkings are trying to prove are the napkin grabber, silverware dispenser, placement roller and the napkin roller. The napkin grabber consists of an exhaust fan with a cover that has holes evenly distributed. The napkin grabber will be able to raise and lower using a pulley system. The fan will be able to suck enough air to capture one napkin. That napkin will then be raised high enough so that the corner of the napkin will catch the placement roller. That roller will force the napkin through to the other side so that it is positioned over the napkin roller. The silverware dispenser will then distribute one fork and one knife. The utensils will land on the napkin and into the silverware roller. The silverware roller will then roll the silverware completely and the rolled silverware will pop out of the silverware roller onto a ramp that will place the rolled silverware in a basket. All real-world applications were considered. This led to several modifications to the design. The Napkings decided to put a blocker so that the silverware falling from the dispenser would not shoot out further than needed. The Silverware dispenser, silverware roller, silverware grabber, and where the silverware exits were all modified for real-world application. Many of the original designs would have been slightly off and non-realistic. By modifying the parts and location, the Napkings were able to produce a model that is realistic in real-world.

Final design

The Napkings are building an automatic silverware roller which will autonomously roll silverware into a napkin for restaurants to use. The product design specification was used to determine the final design of the team’s machine. Its use is to create silverware wrapped in a napkin without human interaction with the exception of filling the silverware racks with the appropriate utensil. The final design is split up into three different sub-assemblies: the napkin grabber, silverware distributor, and silverware roller. Each subassembly was distributed to the group with Trevor and Austin working on the napkin grabber, Lenard and Gabe working on the silverware distributor, and Ryan working on the roller function.


The first function is the napkin grabber. A fan will pick up a single napkin from a stack of cloth napkins using a reverse air flow. The fan is moved on an arm by a stepper motor, from the stack of napkins to the roller. Once the fan reaches the end of the arm, at the roller, the fan stops circulating air which causes the napkin to uniformly drop. Lastly the roller grabs the napkin from the designated drop zone and begins rolling.


The second function is the silverware distributor which is located directly on top of the roller function. The distributor’s function is to drop utensils on top of the napkin to prepare it for the wrapping process. The silverware distributor will have two racks containing forks and knives. With the use of a stepper motor, the silverware will be distributed by rotating wheels with notches. The idea is for as the wheel rotates, the notch will the thick enough to push a single utensil from the stack and force it down to fall on top of the napkin. The distributor’s body will be made of PMMA which is a type of acrylic sheet and will be connected using epoxy glue for a strong hold. As for the moving parts in the function such as the rod a wheel, these parts will be made of wood. The wood material was chosen for these parts as it is easier to cut into cylindrical shapes.


The final function is the roller which will wrap the silverware in a napkin and finish the process. This will be done by the silverware distributor dropping the silverware onto the napkin that was placed in the designated area by the napkin grabber. This process will take place directly over the roller. The weight of the silverware from free fall will push the silverware and part of the napkin into the roller. The roller is made up of three rollers all connected with a sheet of fabric. Two rollers will be stationary while one roller will move in an upside down U-shape. A motor will be connected to the rollers and rotate when prompted. This will roll the silverware in a nice tight roll. Once the rollers spin enough rotations, the silverware will be forced out of the roller and down the ramp that will lead to a basket designated for the roller silverware.
